i sAFE'rY PoIsoN; BOTTLE AND sToPrEit i This inventioni'relate's to newand useful im ovementsm safety'poison bottle and stopper. The -'invention has for an object the'construc tion of a bottle and stopper arranged'in a man- '5 her so that thest'opper once inserted intothe neck of th bottle cannot be removed with the fingers but requires ato'ol for; its removal and thus eliminates the possibility 'of mistaking the poison bottle for some other'bottle in the "dark, or night or other place.-

'Furtheririore, it is contemplated to so arrange the stopper in the neckbf the bottle to eliminate 'thepossibilitypf the sto'p'per becoming loose so that the contents of-the bottle,. especiallyif strong I arrangement of an element upon a'stopper adaptfroin'the bottle. I r

Still further, the invention also proposesan arrangement whereinthe stopper is of arr-incon- ;ed ;to be "gripped with atool for *its extraction ventional shape so as-to eliminate the possibility.

' bottle instead.

v terial part of this disclosure:

of conventionalstoppers being used-in'the safety V v p v of the base'portion and the npperportion ofthe neck of the bottle arefo'r the-following'purposes:

Anotherone'of the 'objec'tsfof this invention is the arrangement" of .coacting means upon the 'stopper and the inn'erkwall of the neck of the bottlel forlatching theistopper in position and necessitating a. turning'tool anda twisting mo;- tion torelease the stopper from its latchedconditiorn 1 Still further the invention proposes the construction of an article as mentioned whichis simple and durable and which may be manufactured and sold atareasonable cost. 7 V

For further comprehension of the invention, and of the objects and advantages thereof; reference will be had to the following description and accompanying drawing, and to the appended claims-in which the various novel features of the invention are more particularly set forth. r

Itis-a" feature ofthis'invention' that the slopes (1') that "the base-portion be adapted "to receive and frictionally hold astopper," (2')" that the upper portion be of a slope so asto be incapable of holding a stopper, and (3) that the upper portion {to base arranged to preventhone s fing'ers-irom' V gripping the stopper for-=its"removal It should be understood that if a'large stopper is obtained and engaged into the upper portion of the outwardly flared continuation B it will not maintain sloping sides.

In Figs. 4 and 5 another embodiment of the invention has been disclosed wherein the neck e of the bottle is of a peculiar shapeneoessitating a similarly shaped stopper and so eliminating any possibility of a foreign stopper being used in the the large angle of I the the lower end of the stem 19.

The stopper I2 is provided with a gripping ele-' ment similargto that previously described. With thisarrangement it is necessary that the particular stopper I2 or a similarly shaped stopper be used in the neck of the bottle and substitu tion of a conventional stopper be made impossible. I In Figs. 6-8 inclusive another embodiment of the invention has been disclosed wherein there" is an arrangement for actually holding thestop- 51 per against removalexcept if removed in a particular fashion. More specifically the neck of the bottle isgshaped similar tof'that described. in Figs. 1 and 2, the same parts may berecognized by the corresponding reference numerals, and the stopper" 12 carries resiliently extended keepers I'l automatically engageable in an internal periph: eral groove 18 in thebase portion of thejneck of the bottle. A stem 19 extends from the topof the stopper and formed with an eye opening 20 for a toolsuchas illustratedin Fig. 3. H V p A means for retracting the resiliently extended keepers I1 is associated withthe keepersand with the stem in a manner so that the keepers-are retracted. upon slight turningof the stern J9. The arrangement comprises a disc 2| -fixed upon arms 22' are eccentrically pivotally mounted. upon the disc and extend in opposite directions and have theirouter ends; respectively pivotallycohnected with the inner ends of the keepers |1., The keepers 11, are urged into extended positions-- by springs 23 acting betweentheirinnerendsand a portion of the stopper.

The stopper [2 is constructed of, tw opieces ce} mented oramalgamatedor in any other manner held together. .-More particularly, thefstopper comprises an upper piece and a lowenpiece 24 of disc shape constituting the lower or bottom end of the stopper. to'the bottom of the upper-portion except at certain areas where the keepers ,ll project.- The lower portion 24 is formed with cavities from which the keepers IT project and in whichrthe springs 23 are disposed. The arms 22 and the disc 2| are arranged in a. cavity 25 formed in the lower portion of the upper port ion of" the stopper. This cavity 25 is circularin shape asclearly illustrated in Fig. 8, but obviously is -not seen from the exterior because of the lower portion 24 of the stopper. a 7 With the arrangement illustrated in Figs.

inclusive the stopper may be pressed in the neck of the bottle as any other, stopper into itsclosed A Pair of oppose This lower piece is cemented position. During the motion of the stopper to its closed position the resiliently extended keepers I! will be depressed by the slopping sides of the neck of the bottle. After the stopper has reached its fully closed position the keepers l I will be urged outwards into the groove la. The stopper cannot now be removed except if a proper tool is engaged upon the eye opening 20, and the stem l9 rotated through substantially 90 so as to cause, the arms-22 120 draw the keepers l1 inwards to disengage the keepers from the groove l8. Then with a longitudinal out- ;wa rd motion the stopper can be withdrawn.

It is to be understood that the stopper may be cork, composition, etc., and that its size and "shape may be varied.

.While I .have shown and described the preferred embodiment of my invention, it is to be 'understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications vcoming within the scope of the invention as defined in. the appended claims."

M Having thus described my inventio what I claimj as new, and desire to secure-by United States Letters Patent is:

:.tf1.-A' safety poison bottle and stopper, com- ,prising a poison bottle having a neck with a base portion adapted to receive a stopper for frictionally holding thestopper and having a top outwardly flared continuation for preventing jonefs fingers from gripping said stopper, and of a slope too steepior frictionallyholding,a stop- ,per, -and a stopper forsaid bottle having resiliently extended keepers automatically engage- .able in an internal groove in the base portion of said neck, a rotatable stem extending from the top of said stopper for engagement with a tool,

andmeans for retractingsaid keepers from rotation of. said stem comprising an element fixed onthe lower endof the stem, and eccentric rods .pivotally connected with the element and with the keepers.
